RIM TOOL.

Application led February 13, 1922. Serial No. 536,245.

To all lwhom it may concern:

Be it known that l, Geenen E. SALL, a

citizen of the United States, residing at Greeley, in the county ot Weld and State ot Colorado, have invented new Improvements in Rim rlools, following 1s a specification.

and use't ul ot vwhich the This invention relates to tire tools. An object of the present invention is the provision of a tool or this ch aracter, by

means of which a rim of the transversely split demountable type ma57 be for the removal ot' a tire and eX contracted panded for replacing the same, with a minimum amount of labor and in a relatively ,short time.`

Another object of the invention is the provision of a tool of this character which for either con quickly adjusted so asto tracting or the provision of a tire d other adis capable so as to enable all space.

With the above and other objects in view,

the invention further includes th e toll owing novel features and details ot construction, to be hereinafter moretullv described, illustrated in the accompanying drawings and pointed out in the appended claims.

Figure 1 isa plan view of the rim of a demountable type with the tool in position for contracting the rim.

Figure 2 is a similar view wi th the toolL in position for expanding the rim.

in detail to the tool partly on for conhe parts in 5 is a section on the line 5 5 of lar view on the line 6-6 1s alike view on the line 7-7 of drawings.

wherein like characters ot' reference denote corresponding parts. the reference character 10 indicates a casing which in cludes substantially parallel side walls 11. The casing 10 is formed to provide a guide for a longitudinally movable bar 12 wh ich extends through each end ot the casing and is provided upon one end with a. sleeve or collar 13. This sleeve or collar 13 surrounds the casing and is capable of being adjustably held against movement in one direction by means ot a dog 111, the latter beingpivotally mounted as indicated at 15 in the collar 13 and adapted for engagement with teeth 16 provided in the edge ot the bar 12. Pivotallv connected to each side of the sleeve or collar 13 as shown at 17, .is an arm 18, the tree ends of these arms lbeingprovided with hooks 19, which are adapted for engagement over the opposite side edges of a rim R. A

PivotallvV secured to the casing 10 opposite the end of the loar 12 which carries' the arms 18, is a pair et arms 20. These last mentioned arms are each pivotally secured to the casing 10 as shown at 21 and lilrethe arms 18 have their outer free ends provided with hooks 22 Jfor engagement over the edges ot the rim E.

Mounted for rotation within the casing 10 between the side walls 11. is a gea-r 23, the teeth ot which engage teeth 24e provided upon the adjacent edge ot the bar 1Q. The gear 23 is mounted upon a short shafft Q5, having` bearings` in the side walls 11 and is engaged by the teeth et a segment 26.', The segment is located between the walls 11 of the casing 10 and is capableot' pivotal movement therebetween and tor this purpose has extending from each side thereotthrough segmental slots 27 in the walls 11. trunnion QS. These trunnions are adapted to be engaged by hooks 29 which are pivotally connected to each side et the casing as shown at 30. Then engaged with the trunnions 28 these hooks Yform a hearing for the said trunnion so that the segiiieiitfba mayv be rocked within this bearing. Extending trom the segment 2G is a handle 31 for convenience of operation.

Then it is desired to contract a wheel rim. the tool is arranged Pin the position shown iu Figure 1 ot' the drawings. that is, with the hooks 19 and 22 ot the arms 18 and 20 respectively, engaged over the edgesA ot the rim R. The hooks 29 are disengaged from the trunnions 28 and the segment 26 and the gear 22 are locked together so as to move as a unit. For this purpose, there is provided a pin 32, which is engageable in slots 33 and 34 provided respectively in movement moves the bar i2 inwardly when the handle 3l is moved in the direction ot' the arrow.

Then it is desired to expand the rim R. the arms 18 are folded inwardl \v along each side ot the bar 12, the hooks 29 are engaged over the trunnions 28 and the pin 32 adjusted so as to permit ot' independent rotary movement between the gear 22E and segment 2G. The segment 26 may then be rocked upon the trnnnions 2S and when the handle 3i is `moved in the direction ot the arrow, the bar l2 will be moved outwardly or in the same direction, thrtaigh the rotary movement imparted to the gear 23.

In order to hold the tool in position when the rim is expanded, the casing l0 is provided with an arm or extension 35 which is adapted to bear upon the edge of the rim when the end of the casing abuts the inner periphery of the rim.

The invention is susceptible of various changes in its form, proportions and minor details ot construction and the right is herein reserved to make such changes as properly tall within the scope ot the appended claims.

Having described the invention what is claimed iszl. A tire tool comprising a easing, a longitudinally movable bar, rim engagingl elements at one end ot the bar, rim engaging elements at one end of the casing, a gear mounted 'for rotation within the easing and engageable with teeth termed on the bar, a segment enlfg'ageable with the gear, whereby the latter may be operated to move the bar in one direction and means for locking the segment and gear together, whereby the bar may be moved in an opposite direction.

2. A tire tool comprising a casing, a longitudinally movablev bar, rim engaging elements at one end of the bar, rim engaging elements at one end ot the casing, a gear mounted tor rotation within the casing and engageable with. teeth 7formed in the bar, a segment engageable with the gear, whereby the latter may be operated to nieve the bar in one direction and a pin and slot connection between the segment and gear, whereby the same may be locked together to move the bar in an opposite direction.

3. A tire tool comprising a casing, a longitudinally movable bar, rim engaging eiements at one end oit the bar, rim engaging elements at one end of the casing, a gear mounted tor rotation within the casing and engageable with teeth termed on the bar, a segment engageable with the gear, a pivotal bearing for the segment, whereby operation of the latter will impart rotation to the gear to move the bar in one direction, means whereby the' segment may be disengaged from the bearing and means whereby the segment and gear may be rocked together to move the bar in an opposite direction when the segment is disengaged from said bearing.

4. A tire tool comprising a. casing, a longitudinally movable bar, rim engaging" elements at one end of the bar, rim engaging elements at one end of the casing, a gear mounted for rotation within the casing and engageable with teeth formed on the bar,y a segment engageable with the gear, pivotallyT mounted hoo-ks forming a bearing for the segment, whereby the latter will impart rotation to thergearto move the bar in one direction and means whereby the segment and gear may be locked together to rock the gear and impart movement to the bars in an opposite direction when the hooks are disengaged from the segment.

ln testimony whereof I amr my signature.
